Highly significant is the presence among Arthur’s warriors of three Celtic deities. Mabon is Apollo Maponos, worshipped in pre-Christian Britain. Manawidan son of Llyr is the Welsh counterpart of the Irish sea-god Manannan son of Ler. Lluch Llauynnauc, there is good reason to believe, was similarly derived from the Irish god of sun and storm, Lugh or Luch Lamhfada.
